Description

Method of attachment between concrete member and another parts
The present invention relates to a kind of method that is used for being provided with cavity at concrete member.Such method can be known from belgian patent 502991.This patent is described and is produced cavity in the formwork by elastomeric material is inserted.This rubber elastomeric material extends through the boundary wall of formwork.Pass the place of the boundary wall of formwork at it, rubber elastomer forms acute angle, so that form bigger cavity owing to the formwork wall is provided with many accessories in above-mentioned place.When concrete is poured, rubber elastomeric material is removed, and tie rod or cable wire are set and by from external action coupling access component tension thereon in the cavity that forms with said method.
An object of the present invention is to be more prone to concrete member and miscellaneous part are coupled.In the prior art, concrete member is provided with outstanding (can be threaded) reinforcement by a concrete member and another concrete member is provided with the cavity that matches with reinforcement is coupled to each other.This cavity is by producing in the formwork of before concrete is poured pipe being packed into.After concrete was poured out, these pipes were still stayed in the formwork.This at first needs suitable cost, because these pipes must be considered to lose, this means considerable expense.Secondly, bonding occurs between concrete and the pipe and between pipe and the reinforcement.
The purpose of this invention is to provide a kind of method that makes concrete member be fixed to external environment.
According to an aspect of the present invention, this purpose realizes in a kind of method that metal parts is fixed on concrete member, may further comprise the steps: the concrete member with the cavity that extends from its outer wall is provided; Formwork is provided; Main body is put into formwork, corresponding with described the cavity at least partly and main body of the shape of this main body comprises elastomeric material in abutting connection with that side of concrete material, when tension force is applied to described main body near described border surface, the mechanical performance of described main body can make its reduced considerable, therefore after concrete is poured and solidifies at least partly, described main body can be removed from the cavity of described shape, and the diameter of described main body can flexibly be dwindled; Perfusion is also solidified concrete at least partly, dismantles described formwork and described body, and described metal parts is fixed in the described cavity.
In this way the length of the cavity of Sheng Chaning (degree of depth) is preferably 20cm.
Can comprise " adhesives " according to a useful embodiment fixing means.The term adhesives is interpreted as using various types of adhesive materials, and this adhesive material provides being connected between the concrete wall of the metal that is introduced into cavity and cavity.The die mould of this cavity preferably is decided to be so that improve bonding.Equally also be applicable to the outer wall of metal parts.
According to a further aspect in the invention, this purpose is by the method realization that is used to be provided with a series of cavitys, and described cavity extends the outer wall up to concrete member in concrete member, and this method may further comprise the steps: formwork is provided; A series of main bodys are put into described formwork, when tension force is applied to described main body, the mechanical performance of each described main body can make near the diameter of main body described border surface that dwindling of considerable arranged, thereby described main body can be removed from the cavity of described shape, dwindling of the diameter of described main body is flexible, and each cavity only comprises by the blind hole of described main part limitation and be basically perpendicular to the boundary wall that the longitudinal length of described main body extends near main body-boundary wall contact surface.
The invention still further relates to the concrete member that will couple with another concrete member, comprise a series ofly being basically perpendicular to the cavitys that described border surface extends at the border surface place by described another concrete member, the boundary wall of described cavity comprises concrete.The invention still further relates to the assembly that comprises two concrete parts secured to one another, comprise an aforesaid concrete member and another concrete member that is located at described concrete member border surface place, described another concrete member has a series of reinforcement, this reinforcement extends into when being couple to the state of described concrete member in the cavity of described concrete member, and the space between described cavity and described reinforcement is filled with the material that described reinforcement is bonded to described concrete main body.
